Product Profile of Internal Heat Re-activated Dryers

Mvs engineering limited offers internal heat re-activated dryers. The dryers are suitable where compressed air of very low dew point is required. Dew point of [-] 60 c or [-] 80 c is achieved by these dryers. The drying unit of these dryers is provided with two vessels. These vessels contain activated alumina or molecular sieves desiccant. These dryers are supplied with electrical heaters. A pre-filter with automatic drain is used to eliminate physical moisture from compressed air before entering air dryer. They come with following salient features:

• A fully automatic unit.

• Pressure is equalized to line pressure before changeover of drying vessels. This prevents pressure and flow surge, and, desiccant dusting

• Low purge air requirement in comparison to heatless type dryer.

• Desiccant life is around 5 years.

• Internal heaters provide maximum heat transfer and reduces power requirement.

• Counter current heated dry purge air removes maximum moisture with minimum gas purge loss.

• Heaters are not in physical contact with the desiccant.

• Standard units produces dry gas / air of [-] 40 c dew point. By using more purge airflow, and using molecular sieves, dew point of [-] 80 c can be achieved.
